The flora of the alpine tundra is characterized by plants that grow close to the ground, including perennial grasses, sedges, forbs, cushion plants, mosses, and lichens. [28] The flora is adapted to the harsh conditions of the alpine environment, which include low temperatures, dryness, ultraviolet radiation, and a short growing season.

The top layer of the understory is the sub-canopy composed of smaller mature trees, saplings, and suppressed juvenile canopy layer trees awaiting an opening in the canopy. Below the sub-canopy is the shrub layer, composed of low growing woody plants. Typically the lowest growing (and most diverse) layer is the ground cover or herbaceous layer.
The Appalachian mixed mesophytic forests is an ecoregion of the temperate broadleaf and mixed forests biome, as defined by the World Wildlife Fund. It consists of mesophytic plants west of the Appalachian Mountains in the Southeastern United States. This ecoregion consists of the following EPA level III ecoregions: Southwestern Appalachians ...

The treeline in Norway is currently moving upwards on average by 0.5 - 1 m altitude each year, with more in some areas. The highest altitude tree in Norway in 2019 was a mountain birch growing at 1,404 m ASL in Jotunheimen. [7] The 1991-2020 temperature normal is significantly warmer than the 1961-1990 normal for all of Scandinavia.
Populus deltoides is a large tree growing to 20–30 m (65–100 ft) tall and with a trunk up to 2.8 m (9 ft 2 in) diameter, one of the largest North American hardwood trees.

These seven can be divided into two main groups. The northern regions of the boreal forest consists of four eco-zones – Taiga Cordillera, Taiga Plains, Taiga Shield and Hudson Plains – that are the most thinly treed areas where the growing season and average tree size progressively shrinks until the edge of the Arctic tundra is reached.
